Have you ever felt like you are walking along a balance beam, trying to remain balanced, but knowing eventually you are going to have to fall off to one side or the other. The anticipation of the fall, in itself can be tiring due to the anxiety of the unknown inevitably brings.

At the same time, you know once you fall, you have only to start again. You may not know where you will be starting from, but at least you know it will start all over again.
